Summary: The dynamics of different isoforms of myosin in skeletal muscle have been studied using a mouse model expressing fluorescently tagged slow and fast myosin. The results showed that the response to protein turnover disturbance varied between slow and fast myofibers. These findings highlight the importance of studying endogenous myosin dynamics in different muscle fiber types.

Summary: Although oncogenic mutations have been found in non-diseased, proliferative non-neural tissues, their prevalence in the human brain is unknown. This study identified oncogenic somatic single-nucleotide variants (sSNVs) in the brains of individuals without tumor diagnoses, with a higher frequency in subcortical white matter and glial cells, and a lower frequency in older individuals. The study also revealed early events in acquiring oncogenic variants, which can contribute to understanding brain tumor origins and improving diagnostics.

Summary: MicroRNAs play a significant role in the genesis of cancer through their regulation of gene expression. MiR-22 can act as both an oncogene and a tumor suppressor gene, with its activity influenced by tissue and environmental factors. Previous studies have reported contradictory findings regarding the role of miR-22 in different cell and tissue types, but in immunocompetent model systems, miR-22 consistently acts as a tumor-promoting miRNA.

Summary: Lack of DNM2 in platelets and megakaryocytes has broad effects, including myelofibrosis and defects in red blood cell development. The absence of DNM2 leads to impaired endocytosis of the TPO receptor Mpl, resulting in elevated levels of circulating TPO. These changes may be attributed to constitutive activation of JAK2 and increased levels of TPO.

Summary: Genetic screens were used to identify modulators of KRAS mutant PDAC sensitivity to ERK inhibitor treatment, leading to the discovery of components of the ATR-CHK1 DDR pathway. Inhibition of CHK1 alone led to apoptotic growth suppression in PDAC cells, suggesting a potential therapeutic strategy in combination with ERK and autophagy inhibitors. Concurrent DDR suppression was found to enhance the efficacy of ERK and/or autophagy inhibitors in KRAS mutant PDAC.

Summary: Biliary tract cancer (BTC) arises from biliary epithelial cells (BECs) in intrahepatic cholangiocarcinoma (IHCC), gallbladder cancer (GC), and extrahepatic cholangiocarcinoma (EHCC). The manipulation of EpCAM-positive BECs in organoid culture has been shown to be crucial for maintaining the characteristics, stemness, and tumorigenic activity of BTC-initiating cells. The syngeneic mouse models recapitulate the pathological features of human IHCC, GC, and EHCC, and could serve as valuable tools for investigating BTC carcinogenesis and developing new therapeutic strategies.

Summary: Formaldehyde (FA) not only exerts cytotoxicity through DNA damage, but also triggers cellular redox imbalance by reacting with glutathione (GSH). GSH synthesis and the enzyme alcohol dehydrogenase 5 (ADH5) play crucial roles in preventing FA cytotoxicity. These findings are important for patients with mutations in FA detoxification systems and suggest potential therapeutic benefits of thiol-rich antioxidants.

Summary: In AML patients, persistence or acquisition of non-DTA mutations during complete molecular remission is associated with worse prognosis, while the inclusion of predictive mutations with DTA genes defines a new group. CHOP-like mutations are significantly linked to inferior outcomes and their detection at relapse is detrimental.

Summary: The high-mobility-group transcription factor Tcf1 plays an essential role in regulating chromatin accessibility and topology, allowing abnormal Notch1 signaling to convey its oncogenic function in T cell acute lymphoblastic leukemia (T-ALL). The formation of a leukemia-prone epigenetic landscape, which is dependent on Tcf1, occurs at the earliest progenitor stage before cells adopt a T lymphocyte or leukemic fate.

Summary: Different subsets of KRAS mutations are detected in different cancer types, and each mutation induces distinct transcriptional responses after activation. These responses may be a result of signaling differences caused by increased protein expression and specific mutation. These distinct responses have an impact on RAS mutational patterning in vivo, with different KRAS mutations preferentially inducing tumor initiation in a cell-specific manner.

Summary: The study found that exposure to thirdhand smoke in utero and during early life significantly affects the immune system and the development of leukemia/lymphoma in mice, particularly more pronounced in male mice. Additionally, thirdhand smoke exposure may contribute to carcinogenesis by lowering the host defense to other toxic exposures.

Summary: The study found that children with acute lymphoblastic leukemia (ALL) were born with higher levels of certain cytokines than controls, with a stronger correlation in children of Latina mothers and those with high hyperdiploidy ALL. Additionally, neonatal cytokine levels were correlated with neonatal levels of endogenous metabolites previously associated with ALL risk.

Summary: The study revealed an association between DNA methylation at the AHRR gene's cg05575921 site and gene deletion numbers in childhood B-ALL cases, and a positive correlation between the polyepigenetic smoking score and gene deletion frequency. These findings further support the idea that prenatal tobacco smoke exposure may influence the generation of somatic copy number deletions in childhood B-ALL.

Summary: The study revealed distinct genomic features of del(9q) in AML patients, including clustered proximal breakpoints within a segmental duplication-enriched region, significant variations in distal breakpoints, and division of the overall deleted region into a proximal constitutional region and a distal oncogenic region. Furthermore, a common overlapped deletion region in the distal part carries multiple genes involved in cancer pathogenesis.

Summary: This study identifies RASA2 as a potential target gene that can enhance the efficacy of T cell therapies for cancer treatment. Ablation of RASA2 increases the activation and cytolytic activity of T cells, leading to improved cancer cell killing. Furthermore, RASA2-deficient CAR T cells have a competitive advantage in the bone marrow and extended the survival of mice in preclinical models. These findings highlight the importance of targeting RASA2 in enhancing T cell therapies for cancer treatment.
